Energy is vital in our daily life because it is a basic human need. Almost all human activities require energy. Oil is a non-renewable energy source. Non-renewable energy comes from sources that will run out or will not be replenished in our lifetimesâor even in many, many lifetimes. (National Geographic Society, 2013). On the other hand, renewable energy, often referred...

According to Ritchie (2019), Oceania emits 1.3 billion tonnes of CO2 yearly, which is equivalent to 1.3% of the global emissions. Wang et al. (2011) argue that most of the carbon emissions are as a result of the generation of non-renewable energy. From figure 8, in 2016, Oceania generated 227.7412GW of non-renewable energy and 67.29998GW of renewable energy. But, in...
